COUNTERBALANCING AND OSCILLA'I'ING DEVICE FOR ELECTRIC HEATERS ANDLAMPS.

Application filed September 14, 1922. Serial No. 588,107.

To all whom it may concern: V

Be it known that I, WILLIAM A. BROWN, a citizen-of the United States,residin in the city and county of Philadelphia, otate ofPennsylvanimhave invented a new and useful Counterbalancing andOscillating Device for Electric Heaters and Lamps, of which thefollowing is a specification.

My invention consists of a novel construcr tion of a. counterbalancingand oscillating device for, an electric, table, .wall orfloor combinedheater, blower and lamp, whereby I provide novel means for enabling theelectriclighting, blowing to be positioned at any angle with respect totheir support, the counterbalancingdevices further havingthe function ofentirelyeliminatingthe vibration of the fan motor which diffuses theheatfromzthe heater and the oscillating device serving, when dosired,.continuallyi and automatically to change the position of. the lampandheating L and blowing mechanism, so that the heat is diffused in alldirections in the room or compartment to be heated, provision being madefor enabling the shade of the lamp effectively to, conceal the operativeparts of the device, in addition to performing its usual function of arefiector,. whereby a.

novel and effective appliance is produced having a plea'singas well-asautilitarian ap-- pearance.

To-the above ends, my invention consistsof a ,-n0vel construction. ofstandard. support or side brackehwhich may-be employed, upon whichispivotallv supported the novel lighting. blowing and heating mechanismand their adjuncts by a suitable arm or and heating devices "controllingthe operation of said devices, so

that, they may be operated singly or in unison.

It further consists of other novel features of. construction, all aswill be hereinafter fully set forth. I For the purpose of illustratingmy ini 'ent!on,I have shown in the accompanying drawings, forms thereofwhich are at present preferred by me, since the same will give inpractice satisfactory and reliable results, although it is to beunderstood that the" various instrumentalities' of which my inventionconsists may be variously arrangedand organzed and that my invention isnot limited to the precise arrangement-andorganization of theseinstrumentalities as herein shown and described.

Figure 1 represents a vertical sectional view of a counterbalancing andoscillating device foran electr c heater and lamp embodying myinvention.

Figure 2 Figure 1, showing the heating. blowing and lighting me hanismsconcealed by the lamp shade and the supporting arm or counterbalancingdevice therefor positioned horizontall flthe base be ng shown insection.

Figure 3 represents on an enlarged scale a section on line 33 Figure 1,showing a portion of the oscillating mechanism whereby the motor blowerand heating devices are automatically oscillated to and fro when idesired.

Figure 4 represents a section on line M Fig. 3.

Figure 5 represents on a reduced scale, a plan view of the dev ceshowing in dotted lines, the different positions the lamp shade and theblowing, lighting and heating elements concealed within it may assume.

Figure 6 represents a vertical sectional view of another embodiment ofmy inven tion. showing the same applied to a wall bracket.

Figure 4 represents a side elevation of Figure 6, showing the heatingand blowing devices inclined downwardly at an angle from the horizontal.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

In carrying out my invention, which. it

represents a side elevation of or itsequivalent '7, whereby 25,eonhection canbe tightened or loosened, ac-

the upper ring 1?,

50 or casing, which is tor casing will be understood is adapted for a.floor lamp, a table lamp or a wall lamp, I have shown my invention inFigs. 1 to 5 as adapted to a floor or table lamp, and in Figures 5 6 and7, I have shown my invention as adapted to a wall bracket, or, in otherwords, adapted to be supported from the vertical side wall of a room orcompartment.

Referring first to Figures 1 to 5, 1 desig- 10 nates my novelconstruction of lamp, the

same being shown as provided with a suitable foot or base. 2, on whichis supported a standard 3, which ma be hollow and serve as a containerfor the electrical connection 4.

desi nates athreaded rod or pivotal connection, which passes through theupper end of the standard sand also through the farm or arms 6, two ofaid arms being pref- ;,ei-ably employed, which are located on eachsid'pf the standard 3 and the rod or pivotal connection 5 heing threadedatone or both "(if it's endsand being provided with the nut the pivotalcording to requirements. If both ends of fthe rod are threaded, it willbe evident that twonuts Twill be employed, or, if desired, one ofsaidlnuts may be integral with said r'oda'nd only a single nut employed.

The ends 8 of the arms 6 are attached by s uitabl 'me m e to the ring10. which surrdunds the motor casing 11. which? has the trunnions 39rotatable in said ring, so that the" lower, heater and their adjunctscan -to the members'13 of angle-shaped brackets.

' whose lower pendant members 14- are secured to the uprightrods 15,which are. secured at their bottom ends to the bottom ring 16, the"upper ends of said rods 15 being secured to said uprights 1.5. lowerrings 16 and upper rings 17 constituting a skeleton frame or support forthe lamp shade 1S. i 19 rlesignatesan open-ended support, ring bolted orsupported at its lower portion upon the laterally extending members 13and in the upper portion of the casing or frame 19. hich is open-endedand of any desired contour, I locate the electric heater 20, which maybe of anysuitable construction and composed of a series of heatingcoilsor resistance coils of any desired construction.

91 designates a motor shaft, which has secured to its upper end the fanor blower 22.

the latter being positioned between the mo- 11 and the electric heater2.0.

23 designates the conductors leading to the h ater 20, and 24 designatesthe conductors v6 ich lead to the electric lights 25. any rlesirednumber of which, as two, three or four, or more, may be employed. Theelectric lights 25 are supported in suitable sockets,

which may be attached to the arms 8 in any suitable manner.

It will be obvious that my invention may be. employedin connection witha fan or blower which is stationary, that is, incapable of oscillatorymovement, as seen in Figure 6, if desired, or I may provide means forenabling the blowing and heating mechanism automatically to beoscillated to and fro, so that the heat will be diffused into everyportion of the room or apartment, and in carrying out this feature of myinvention, I employ the construction shown in Figures 1, 3 and 4, fromwhich latter figures it will be apparent that the motor shaft '21 isprovided with a worm 26, which is in mesh with the gear 27, which ismounted on the. shaft 28. The shaft 28 is provided with a worm 29,whereby motion is imparted to the gear 30, which ismounted upon theshaft 31, which carries the disk or head 3?, which has one end of thelink 33 eccentrically connected thereto at 34, the upper or opposite endof said linklieing connected at the fixed point- 35 to the ring or frame10.

By'the turning or manual adjustment of the finger piece or head 36, theportion 37 is caused to frietionally engage the surface 38, whereuponthe rotation of'the worm 26" and the gear 27 is communicated to theshaft 31 and head or disk 32, so that oscillatory r'novemenl; may be imarte'd to thejink'33 whenever desired, it ereupon the blower casing 11oscillates on the diametrically disposed trunnion 39.

It will thus be seen from the foregoing that I have provided twoparticularly novel features in connection with my im cntion. the firstrelating to the counlerhalancins of" the principal operative partsbymeans of the elongated weighted arms 6, whereby the blowing andheating elements togetherwith l the shade 18 may be positioned at anydesired angle to the horizontal or vertical plane" upon loosening thenut 7, the other featur of my invention relating to the oscillatingmovement which is imparted to the heating and blowing mechanism andtheir adjuncts. the electric heating device,blower, and shade moving asa unit. and the construction being such that the blower. electric heaterand the shade all are caused to function in unison and, in addition.automatically to oscillate when desired, whereby the heat is diffusedinto every portion of the room or compartment to be heated.

It will he further apparent that the elon gated arms 6 which are made ofconsiderable length and weight to suit requirements. the weight of saidarms to one side of the pirotal connection 5 being designed so asefiectively to balance the weight of all the other eleinent's oil theother side of the pivot," pivotal connection or rod 46 passing therehavea dual function since they not only ef through andalso through the arms47, which fectthecounterbalancing of the'device acare provided at theirinner ends with the cording torequiremen'ts, but, in additioinfweightedor *counterbalancing devices 48, 'by reason of thei'r wei'ght they takeup and which may beof ornamental design and are To [in practice totallyeliminate all the vibra- 'j'oined by'the't-ransverse connection 49, thetion of the motor 11, so that no matter at outer ends of the arms 47beinglaterally what speed the motor or blowing apparatus andupwardly'deflected as indicated at 50 is operated, no vibration ispresent. and carrying the open-ended casing, guard l Imake'no claim tothe oscillating mechaor frame 51 ofany desired contour, and nism, perse, seen in Figs. 3 and 4, and I being secured to the electric motorcasing have deemed it' unnecessary to describe the llby the connections52. same in greater detail, as the oscilla ting, The arms 50 alsosupport the sockets for mechanism per se is employed in electrictheelectric lights 53 and within the casing, fans, but I am thefirstintheart to employ'bl is located the electric heater-2O of-the in.conjunction with oscillating blowin same construction as alreadydescribed. mechanism; of the character abovedescrlbfl 54 designates theelectrical connections'to electric heating and li 'hting mechanism intheheater'QO. 55 designates the electric cond'ependently controlled andpositioned and motions t th l mp 53, nd"56 de i t functioning as aboveexplained, and I am the electrical connections to the motor 11":
